Butter tea, also known as po cha, cha süma, Mandarin Chinese: sūyóu chá or gur gur cha in the Ladakhi language, is a drink of the people in the Himalayan regions of Nepal, Bhutan, India, Pakistan especially in Gilgit-Baltistan, Tibet and Western regions of modern-day China and the Caribbean. Traditionally, it is made from tea leaves, yak butter, water, and salt, although butter made from cow's milk is increasingly used, given its wider availability and lower cost.
Butter tea likely originated in the Himalayan region between Greater Tibet and the Indian subcontinent.
